POWER AND SPEED RE GULATOR.

SPECIFICATEON forming part of Letters Patent No. 335,541, dated February2. 1886.

Application filed Novemhlr 17, 1885.

To all whom it may concern:

Be it known that I, CHRISTIAN ROWLAND, of Lanark, in the county ofCarroll and State of Illinois, have invented a new and usefulImprovement in Power and Speed Regulators, of which the following is adescription.

Figure l is a sectional side elevation of the device, and Fig. 2 is asection through the line as x.

Hy invention is in the nature of a device for regulating the power orspeed of ma chines run by hand or horse power, or other varying andirregular power; and it consists in the combination of a ratchet-clutchmechanism, a driven shaft, and a fly-wheel rigidly fixed to the shalt ata point between the driver-section of the clutch and the point ofutilization of the power, as hereinafter described.

In the drawings, A represents a flanged hub, which is rigidly fastenedto a shaft, B, by a set screw or other device. Between the flanges ofthishnbareloosely hinged the pawls a a. Turning loosely on the shalt,and covering the hub with its pawl or pawls, is a cupshaped wheel, C,whose inner periphery is wrought into rat hetteeth b. The outer face orperipheryof this wheel is made as a smooth band-pulley; but it may be atoothed wheel, or any other form of driving-wheel. On the shalt B issecured rigidly ally-wheel. D. Now, it being borne in mind that thewheel 0 is the driver or source of power, and the shaft- B is connectedwith the driven machinery or pointof utilization of power, it will beseen that wherever the speed of the wheel Cexceeds that of the shaft theratchet-teeth b of said wheel engage the pawls of the hub and transmitthe power to the shaft, but when from any cause the speed of wheel 0falls off from the slacking up of the horse or other power the mo lSerial No. 183,135. (No molel.)

mentum of the flywheel causes the shaft to maintain for a while itsmaximum speed, and it then revolves more rapidly than the wheel 0, inwhich case the hub with its pawl or pawls a turns inside the wheel 0over the ratchet-teeth b. By this means the irregularities of the speedat the source of power is compensated for and rendered more uniform atthe point of utilization.

I am aware that a ratchet-clutch which has a fly-wheel on thedrivel-section of the clutch has been introduced in the train ofmechanism of a sewi ng-machiue. XVhen, however, the flywheel is locatedon the d riversection of the clutch, the advantages which my inventionsecure cannot be obtained, since in my case the function of thefly-wheel is to continue the motion of the driven mechanism after thedriver-section ol'the clutch isinaetive orslower than that of thedrivenmechanism. Thelocation of the lly-wheel on the driven side of the clutchis then fore very important, since it continues the motion of the drivenmachinery without requiring it to turn all of the machinery back of theclutch or between it and the source of power.

Having thus described my invention, whatI claim as new is A train ofmechanism between the source of power and point of utilization,consisting of a shalt, B, a driving-wheel, C, loose on the shaft, aclutch-hub fixed rigidly on the shaft and connected to the drive-wheelby ratchet and pawls, and a fly-wheel rigidly fixed on the shalt betweenthe clutch and the point of utilization of the power, substantially asdescribed.
